[0001]
BACKGROUND OF THE INVENTION
The present invention is a changer-type disk device capable of reproducing and / or recording information on a disk such as a CD (compact disk) or a DVD (digital versatile disk) and storing a plurality of disks in the apparatus. In particular, the present invention relates to a slot-in type changer-type disk device that automatically conveys a disk inserted from an insertion slot to a predetermined position.
[0002]
[Prior art]
In a vehicle-mounted changer disk device, a slot-in method in which a disk inserted from an insertion port is automatically transported to a predetermined position by a disk transport mechanism is often used. In such a changer disk device, a disk is rotated. A drive unit that drives and reproduces and / or records information by an optical pickup and the like, and a disk storage unit that can store a plurality of disks arranged in the thickness direction are provided. The drive unit moves forward and backward between a drive position and a retracted position by a drive drive mechanism, and at this drive position, one of a plurality of disks held in the disk storage portion is selectively pulled out. The selected disk is rotationally driven by the drive unit.
[0003]
2. Description of the Related Art Conventionally, in such a changer type disk device, a plurality of stockers are arranged as a disk storage portion so as to be movable up and down. Such a disc storage portion includes an arcuate stocker capable of holding the outer peripheral edge of the disc over about a half circumference, and a plurality of feed screw members having spiral grooves with unequal pitches, and is arranged in a stacked state. Each feed screw member is inserted into and screwed into a plurality of stockers, and these feed screw members are rotated synchronously, so that each stocker holding the disk can be moved up and down in the axial direction of the feed screw member. Yes.
[0004]
For example, when a disc inserted into the apparatus is held by a desired stocker, if the stocker is placed at the same height as the disc transport path, the disc is transported to the back side of the device by the disc transport mechanism. The disc can be held on the inner periphery of the corresponding stocker. Further, when the selected disc held in the desired stocker is pulled out to the play position, the stocker is arranged at the same height as the disc transport path, and the selected disc held in the stocker is moved to the front side of the apparatus. The selected disk can be taken out from the inner periphery of the stocker and clamped to the drive unit. An arc-shaped holding groove is formed on the inner peripheral portion of the stocker so that the outer peripheral edge of the disk can be inserted over almost half of the circumference, and the position of the disk is regulated in the thickness direction and the radial direction by the holding groove. It is held in the state.
[0005]
[Problems to be solved by the invention]
According to the above-described conventional changer-type disk device, the stocker is moved up and down in a state where the drive unit capable of moving back and forth is disposed at the retracted position, and the drive unit holds the drive unit on the stocker. Since it can be configured to overlap, there is an advantage that it is possible to reduce the size by effectively using the space in the apparatus. However, since the stocker engages with the spiral groove of the feed screw member and moves up and down, a small clearance is required between the stocker and the spiral groove, and the disk held by the stocker has manufacturing dimensions. Due to the variation, it is necessary to set the inner diameter dimension of the holding groove of the stocker to a dimension that can accommodate the predicted maximum diameter disk. Further, in the slot-in type changer type disk device, since obstacles cannot be arranged on the disk transport path from the insertion slot to the stocker, the holding groove of the stocker can be provided only up to about a half circumference (about 180 °) of the disk. Therefore, it is difficult to hold the disk sufficiently with this stocker. For this reason, when a desired selected disk is pulled out from the stocker and a play operation is performed, if external vibration from the vehicle is applied to the changer-type disk device, the other standby disk left in the stocker vibrates and rattles. There was a problem that abnormal noise called noise occurred. Such rattle noise is very annoying when playing music or the like recorded on a disc by a play operation.
[0006]
The present invention has been made in view of the actual situation of the prior art, and an object of the present invention is to provide a changer-type disc device capable of suppressing rattle noise generated during a play operation.
[0007]
[Means for Solving the Problems]
In the present invention, when a drive unit is moved to a drive position by a drive drive mechanism and a desired selected disk is being played, a standby disk remaining in the disk storage unit is pressed from the outside in the radial direction by a pressing member. When the drive unit is moved to the retracted position by the drive driving mechanism, the press contact of the pressing member to the standby disk is released along with the operation of the drive driving mechanism. With this configuration, the pressing member can be pressed against / released from the outer peripheral edge of the disc along with the operation of the drive drive mechanism, so that the pressing member is placed on the outer peripheral edge of the standby disc remaining in the disc storage portion during the play operation. , The rattle noise generated from the standby disk can be reduced.

The spring 41 is slightly rotated in the clockwise direction, and the regulating plate 42 is in pressure contact with the outer peripheral edge of the disk D at a position below the transport path of the disk D (a position below the selected disk D at the play position). As a result, when the desired selected disk D is pulled out to the play position, the disk D below the selected disk D has a spring force due to the bending of the pressing portion 40c of the second pressing member 40 and the coil spring 41. The rattle noise generated by the vibration of each standby disk D held by the stocker 21 is reduced by being urged toward the stocker 21 from the outside in the radial direction. Therefore, when the desired selected disk D is pulled out to the play position, the position of all the standby disks D left in the stocker 21 is regulated by both the first pressing member 25 and the second pressing member 40 described above. Thus, the rattle noise generated by the vibration of the standby disk D can be reliably reduced. In the above embodiment, the pressing portion 40c of the second pressing member 40 is pressed against the standby disk D mainly by the elastic force of the coil spring 41, but the through hole 40d of the second pressing member 40 is The pressing portion 40c may be further pressed against the outer peripheral edge of the standby disk D by pressing the pressed piece 40f formed on the inner peripheral edge with the protrusion 36a.

[0041]
Next, the configuration of the drive unit 7 will be described. As shown in FIGS. 21 and 22, the drive unit 7 has a horizontally long bracket 60 mounted on the drive chassis 30 so as to be movable in the front-rear direction, and the above-described lateral holes 7 a and 7 b are formed in the bracket 60. Is provided. A spindle motor 61 is attached to the central portion of the bracket 60, and a turntable 62 is fixed to the rotation shaft of the spindle motor 61. An optical pickup 63 and a support plate 64 are mounted on the bracket 60, and the optical pickup 63 and the support plate 64 are disposed to face each other with a spindle motor 61 interposed therebetween. The optical pickup 63 meshes with the screw shaft 65, and the optical pickup 63 is rotated in the axial direction of the screw shaft 65 (radial direction of the disk D) by rotating the screw shaft 65 with a thread motor (not shown) as a drive source. It is to be transferred.
[0042]
The support plate 64 is formed in a U-shaped cross section, and this support plate 64 moves back and forth inside the drive portion 25d of the first pressing member 25 described above (see FIGS. 13 and 14). A clamper 66 is rotatably supported at the top end of the support plate 64, and the disk D is chucked between the clamper 66 and the turntable 62.

Yes. Further, a drive pin 68 a is implanted at one end of the drive plate 68, and this drive pin 68 a protrudes in the direction of the slide cam plate 34 and the cam plate 54.
[0043]
The clamping operation of the disk D will be described with reference to FIG. 20 first. First, as shown in FIG. 20D, the slide cam plate 34 moves to the foremost side (the left side in the figure) of the second chassis 4. When the drive unit 7 is in the retracted position, the clamper 66 is released from the turntable 62 as shown in FIG. At this time, the lock groove 55a of the lock plate 55 is engaged with the pin 59 of the slide cam plate 34, and the drive piece 34b of the slide cam plate 34 and the drive piece 54b of the cam plate 54 are displaced in the front-rear direction and face each other. is doing. When the drive unit 7 moves from the retracted position to the drive position, the drive pin 68a of the drive plate 68 passes directly below the drive piece 54b of the cam plate 54 and faces the drive piece 34b of the slide cam plate 34. The state is maintained as it is.
[0044]
When the slide cam plate 34 moves to the back side of the second chassis 4 by the rotation of the rotation arm 36 after the drive unit 7 moves to the drive position, the lock pin 32 is camped as shown in FIG. Since the hole 53 a moves from the lower stage to the upper stage, the drive chassis 30 rises together with the drive unit 7. Further, when the lock groove 55 a of the lock plate 55 is engaged with the pin 59 of the slide cam plate 34, the cam plate 54 that moves to the back side together with the slide cam plate 34 is illustrated by the engagement of the guide hole 54 a and the pin 57. Since it rotates slightly clockwise and moves to the back side of the second chassis 4 while maintaining the horizontal posture, the drive piece 54b of the cam plate 54 presses the drive pin 68a of the drive plate 68 during this movement. As a result, the drive plate 68 rotates in the direction of arrow A in FIG. 21A and moves the slide plate 67 in the direction of arrow B, so that the support plate 64 moves down together with the clamper 66 as shown in FIG. The clamp 66 is brought into pressure contact with the turntable 62 via the disk D.
[0045]
When the slide cam plate 34 further moves to the back side of the second chassis 4, as shown in FIG. 20B, the upper surface of the cam portion 55b of the lock plate 55 contacts one pin 57 and rotates downward. The lock groove 55 a of the lock plate 55 comes off from the pin 59. As a result, as shown in FIG. 20A, the cam plate 54 and the lock plate 55 are moved to the left side in the figure by the elastic force of the coil spring 56, and the drive pieces 34b and 54b of the slide cam plate 34 and the cam plate 54 are It is sufficiently separated from the drive pin 68a. As described above, in this case, the drive chassis 30 on which the drive unit 7 is mounted is elastically supported by the second chassis 4, and the selected disk D is played in this state.
[0046]
Next, the operation of the changer type disk device configured as described above will be described. As described above, the changer-type disk device according to the present embodiment is a disk reproducing device that can reproduce a disk D (small diameter disk) having an outer dimension of 8 cm and a disk D (large diameter disk) having a diameter of 12 cm. Hereinafter, a play operation for selectively reproducing a plurality of large-diameter discs D stored in the stocker 21 will be described.
[0047]
When a desired selected disk D is played from a plurality of disks D held by each stocker 21, first, the drive unit 7 is moved to the retreat position (see FIG. 11) farthest from the stocker 21, and this In this state, the large-diameter gear 16 is rotated, and the stocker 21 holding a desired selected disk is raised or lowered to a height position equivalent to the conveyance path of the disk D. At this time, as shown in FIG. 13, since the outer surface of the support plate 64 of the drive unit 7 is in contact with the tip of the drive portion 25d of the first pressing member 25, the first pressing member 25 is clockwise in the figure. The position of the disc D held by the stocker 21 is released, and the pressing force from the first pressing member 25 is released. Further, as shown in FIG. 18, since the rotation arm 36 restricts the rotation of the second pressing member 40, the disk D held by the stocker 21 receives the pressing force from the second pressing member 40. It becomes a released state. Therefore, all the disks D held by the stocker 21 can be raised or lowered without being obstructed by the first and second pressing members 25 and 40.
[0048]
Next, the toothless gear 37 is rotated counterclockwise in FIG. 18 by using a third motor (not shown) as a drive source, and the first idler gear 45 meshing the rotational force of the toothless gear 37 with the tooth portion 37a. The drive unit 7 is moved from the retracted position to the play position (see FIG. 12) by transmitting to the arms 50 and 51 via a gear group such as. Thereafter, the first motor described above is rotated, the guide body interval changing mechanism including the slide plates 11 and 12 is driven, and the first and second guide portions 9 and 10 are moved toward each other. Then, as shown in FIG. 4, the desired disk D selected between the transport pulley 13 and the transport guide body 15 is sandwiched, and in this state, the innermost transport pulley 13a is rotated, so that it is shown in FIG. Thus, the selected disc D is pulled out to a play position that can be driven by the drive unit 7. Whether or not the selected disk D is pulled out to the play position is detected by pressing a switch (not shown) installed in the guide groove of the transport guide body 15 to the outer peripheral edge of the disk D.
[0049]
When the drive unit 7 has moved to the drive position, the tooth portion 37a of the toothless gear 37 and the first idler gear 45 shift to the non-meshing state, and each rotation arm 36, As the 44 rotates, the slide cam plates 33 and 34 move from the near side to the far side on the inner side surface of the second chassis 4. Here, while the slide cam plate 34 moves from the position shown in FIG. 20D to the position shown in FIG. 20C, the drive chassis 30 on which the drive unit 7 is mounted rises, so that the center portion of the turntable 62 is played. The center hole of the selected disk D that has been drawn to the position enters the center hole, and the centering operation of the selected disk D is reliably performed. Further, since the drive piece 54 b of the cam plate 54 presses the drive pin 68 a to rotate the drive plate 68, the clamper 66 descends together with the support plate 64, and the selected disk D centered on the turntable 62 is moved by the clamper 66. A clamping operation for crimping is performed. After the selection disk D is chucked on the turntable 62, the transport pulley 13 and the transport guide body 15 are moved in the directions farthest away from each other, so that the selected disk pulled out to the play position as shown in FIG. D can rotate freely.
[0050]
When the slide cam plate 34 moves from the position shown in FIG. 20 (c) to the position shown in FIG. 20 (a), the drive chassis 30 is fixedly supported on the second chassis 4 by the drive lock means described above. The lock mode is released, and the switching operation to the vibration isolation mode elastically supported by the damper member 31 or the like is performed, and the drive unit 7 mounted on the drive chassis 30 is pulled out to the play position in this vibration isolation mode. The selected disk D is reproduced. As the drive unit 7 moves from the retracted position to the drive position, the support plate 64 of the drive unit 7 moves away from the drive part 25d of the first pressing member 25 as shown in FIG. Since the projecting piece 34a located outside presses the side edge of the first pressing member 25 as the slide cam plate 34 moves, the first pressing member 25 slightly rotates counterclockwise to restrict the plate. 27 is pressed against the outer peripheral edge of all the standby disks D located above the selected disk D drawn out to the play position. Further, as shown in FIG. 19, the second pressing member 40 receives the elastic force of the coil spring 41 and rotates slightly in the clockwise direction as the rotating arm 36 that operates the slide cam plate 34 rotates. Then, the regulating plate 42 fixed to the second pressing member 40 comes into pressure contact with the outer peripheral edges of all the standby disks D located below the selected disk D drawn out to the play position. Therefore, when the selected disk D is pulled out to the play position, all the standby disks D remaining in the stocker 21 are pressed in the radial direction (stocker 21 direction) by the first and second pressing members 25 and 40. The rattle noise generated by the vibration of the standby disk D can be reduced.
[0051]
In this embodiment, the disc storage unit 6 includes six stockers 21. For example, when the disc D held in the third-stage stocker 21 is selected and pulled to the play position, the first and second stages The positions of the two standby disks D held by the eye stocker 21 are regulated by the first pressing member 25, and the three standby disks D held by the fourth, fifth, and sixth stage stockers 21 are the second ones. The position is regulated by the pressing member 40. At this time, the regulation plate 27 of the first pressing member 25 is formed with one fewer taper grooves 27 a than the stocker 21, and the interval between the taper grooves 27 a is above and below the spiral groove 19 a of the feed screw member 19. Since it is set to be equal to the equal pitch portions at both ends and the restriction plate 42 of the second pressing member 40 is similarly configured, all the standby disks D left in the stocker 21 are positioned in the radial direction and the thickness direction. Therefore, the generation of rattle noise can be reliably reduced.
[0052]
When the selected disk D pulled out to the play position is stored in the stocker 21, first, the rotating gears 36 and 44 and the slide cam plates 33 and 34 are rotated by rotating the toothless gear 37 in the opposite direction. Is moved to the position shown in FIG. While the slide cam plate 34 moves from the position shown in FIG. 20 (a) to the position shown in FIG. 20 (d), a clamp releasing operation and an operation for shifting from the anti-vibration mode to the lock mode are performed. When the conveying guide body 15 is brought close to the innermost conveying pulley 13a and the innermost conveying pulley 13a is rotated in the reverse direction, the selected disk D pulled out to the play position is returned to the empty stocker 21. When the toothless gear 37 further rotates in the opposite direction and the tooth portion 37a meshes with the first idler gear 45, the rotational force of the toothless gear 37 is transmitted to the arms 50 and 51, so that the drive unit 7 is driven. The disk D moved from the position to the retracted position, and the pressing force from the first and second pressing members 25 and 40 is released again.
[0053]
In the above embodiment, the restricting plates 27 and 42 are fixed to the first and second pressing members 25 and 40, respectively, and the restricting plates 27 and 42 are pressed against the periphery of the disk D held by the stocker 21. However, the restricting plates 27 and 42 are not necessarily provided, and the pressing portions 25c and 40c of the pressing members 25 and 40 may be brought into direct contact with the disk D. In this case, it is also possible to form tapered grooves formed in the restricting plates 27 and 42 in the pressing portions 25c and 40c. Further, the shape and material of each of the pressing members 25 and 40 can be appropriately changed. When the drive unit 7 moves from the retracted position to the drive position, the outer peripheral edge of the disk D held by the stocker 21 is inserted into the insertion opening 2a side. As long as it can be pressed and urged toward the stocker 21 side.
[0054]
【The invention's effect】
The present invention is implemented in the form as described above, and has the following effects.
[0055]
When the drive unit is moved to the drive position and the desired selected disk is being played, the standby disk remaining in the disk storage portion is pressed in the radial direction by the pressing member. The rattle noise generated by the vibration of the standby disk remaining in the storage portion can be reduced, and when the drive unit is moved to the retracted position by the drive drive mechanism, the drive drive mechanism is operated. Since the pressing member is separated from the outer peripheral edge of the disk, when the disk is stored in the disk storage part or when the disk stored in the disk storage part is selected, the movement of the disk is prevented by the pressing member. Can be prevented.
